Hi,

what do you register? And -- when you create new ones -- you have more
than two components? I don't quite get it ...

That's the form?

Why don't you write your manager class manually and display the
editors for houses and persons as children? You can use the #onAnswer:
handler of the Magritte components to get notified when the user hits
add (save).
I don't quite understand why you need MAToManyRelationDescription and
a custom MACheckedMemento.
Cheers,
